| abstractText | gp130 is a common signal-transducing receptor component for the interleukin-6 (IL-6) family of cytokines. To investigate the expression of gp130 in T-cell subsets and its regulation, anti-murine gp130 monoclonal antibody (MoAb) was used for flow cytometric analysis. In normal mice, gp130 was differentially expressed in thymocyte and splenic T-cell subpopulations defined by CD4/CD8 expression. In aged MRL/lpr mice, although gp130 expression was detectable in splenic CD4(+) or CD8(+) T cells, gp130 expression was significantly downregulated. Because serum levels of IL-6 and soluble IL-6 receptor (sIL-6R) are elevated in these mice, we examined the possibility that the downregulation of gp130 expression on splenic T cells might be produced in response to continuous activation of gp130 by high levels of serum IL-6. In transgenic mice overexpressing IL-6, gp130 expression in the splenic T cells was significantly decreased. After stimulation with IL-6 in vitro, the level of gp130 on CD4(+) or CD8(+) splenic T cells from normal mice was significantly decreased. These results suggest that the expression of gp130 in splenic T cells could be downregulated by the IL-6 stimulation under physiological or pathological circumstances. |
